UCTRONICS IEEE 802.3af Micro USB Active PoE Splitter Power Over Ethernet 48V to 5V 2.4A for Tablets, Dropcam or Raspberry Pi 2/3B+ (48V to 5V 2.4A)

I've been using this to power an older Intel Compute Stick running Home Assistant. Perfect source of power (from my backed-up PoE switch), ethernet (the old Compute Stick had none), and an extra flash drive that I have set up as a SWAP partition, as the compute stick came only with 1GB ram... A perfect use case for an old device that would otherwise get discarded...

This has proven to be an excellent choice to power a Raspberry Pi 3b project. I built it inside an enclosure with a 7" LCD screen and this adapter powers both the Pi and the screen using PoE. The application running on my pi is not CPU intensive so I can't comment on how far the power delivery can be stretched, but it has been going for months now without a failure. This was easy to integrate and an inexpensive alternative to the official rPi3b PoE hats that I've seen.

Work as described!

This adapter is perfect for a device that does not support POE power out of the box. This adapter is connected to a TPLINK travel router that I am using for all of my alexa IoT devices as those aren't really the best when ut comes to network security. The POE port that the device is using is on a separate Vlan on my switch and it has no issues providing network data as well as power over the Ethernet cable. All in all, works as described.

The only feature that could make this a full 5-star review would be if this had a 90-degree connector for the power wire. It looks wonky for both wires to be sticking straight out of adjoining sides of the Pi case. But it works well, it's a smart product for a niche use case. I bought 2, if they last a few months we'll get another 5 for the cluster.

Its works fine - I originally tried to use a Ubiquity injector with this. However it didn't work. I thought the problem was this but it was the fact that the Ubiquity injector isn't compatible with this device.

Exactly as described .. works well

Works perfectly. My switch recognizes it as a class 3 PoE device, and typically consuming 3.1 to 3.5 watts of power. It plugged right into my pi (with a 3.5" display) and so far I have not found any problems. The only thing I'd mention is there's no clear indication of which network connection faces the switch, and which faces the client device. I took a guess that with the male RJ45 and micro-usb cable being the same length, that was where the pi should go, and I was correct. (I include a picture of the "correct" manner of connecting it.)

bought this to replace the one from Aliexpress, about the 2X of the price, order from Aliexpress will take too long, so far so good.

It worked for a year and then broke, better buy from local shops with warranty

If you have an existing Power over Ethernet (PoE) network, this device lets you connect USB-powered devices to it without needing a separate power supply. I used it to add a wireless access point (WAP) to my network in a location that didn't have mains power available for a conventional USB power supply for the WAP. No configuration needed, works straight out of the packet. Quality is o.k. but nothing special. No idea how durable it is, has only been in use for about a month. No problems so far.

PoEは一般的にはまだまだ知られていませんが、PoE HUBを有していてコンセントが不足気味な当方にとって、検証の際に助かっています。 ただ、連続稼働の現場に投入するか、といえば現時点では？です。

replace outdoor camera, but it was powered by POE, bought Wyze camera, so this cable works great cover the PEO to micro USB
